A 4-pin ribbon-style jumper cable with 2.54mm (0.1") pitch connectors on both ends. A neat, reliable way to connect standard 0.1" header devices — perfboard, breadboards, breakout boards, and more — without using loose individual jumper wires.
These connectors are sometimes referred to as "Berg", "Dupont", or "Molex" style — they're a widely used generic standard. The connectors are not keyed or latched, so they can be inserted in either orientation.
Key Features
- 4-Pin Configuration – 1×4 ribbon-style cable with female headers on both ends
- 2.54mm (0.1") Pitch – Standard header spacing, compatible with most breakout boards and perfboard
- 20cm Length – Convenient length for bench work and prototyping
- Non-Keyed Connectors – Can be inserted in either direction
Ideal For
- I2C and SPI sensor connections (SDA, SCL, VCC, GND)
- Prototyping with perfboard and breadboards
- Connecting 4-pin modules and breakout boards
Package Contents
- 1× 4-pin jumper cable (20cm, female-to-female)
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
